Abstract
Simple Serial Port is an open-source Internet of Things (IoT) project. Simple C++ serial port communication with an Arduino for Windows. This library allows a simple-serial-port communication integration into any Windows C++ application that intends to communicate with any Ardunio. Reading from the Serial port uses common delimiters, such as JSONs, which are then concatonated at the beginning and at end of each string sent from the Ardunio. It is built using C++, Arduino. Key capabilities include: Write to Serial port; Read from Serial port; Close connection when needed. The complete source code is publicly available on GitHub under the MIT License, making it a useful reference for students building an Internet of Things (IoT) mini project or final-year project.
1. Introduction
This library allows a simple-serial-port communication integration into any Windows C++ application that intends to communicate with any Ardunio. Reading from the Serial port uses common delimiters, such as JSONs, which are then concatonated at the beginning and at end of each string sent from the Ardunio. Examples are provided further below.
During a university project which used an Arduino and a C++ program, we had some issues establishing a quick and easy serial port communication system. This project was then created, after the semester, to create an easy to use lightweight serial communication library.
2. Objective
Simple C++ serial port communication with an Arduino for Windows
This project demonstrates how C++, Arduino can be applied to a real-world Internet of Things (IoT) problem.
3. Key Features / Modules
- Write to Serial port
- Read from Serial port
- Close connection when needed
4. Technology Stack
5. System Requirements
General requirements for this technology stack — check the README for exact versions.
- Arduino IDE / PlatformIO or a C++ compiler (g++)
- Target board (e.g. Arduino, ESP32) where applicable
- Git (to clone the repository)
6. Installation & Setup
git clone https://github.com/dmicha16/simple_serial_port.git
cd simple_serial_portFull setup instructions are in the project README.
7. Future Enhancements
Suggested extensions you can add to make this your own project.
- Add a mobile dashboard using Blynk or Firebase
- Store readings in a cloud database for history charts
- Add alerts via SMS / Telegram when thresholds are crossed
8. Viva / Review Questions
Common questions examiners ask for projects in this domain.
- Which microcontroller / board and sensors are used and why?
- How does the device send data (Wi-Fi, MQTT, HTTP, Bluetooth)?
- Where is the sensor data stored and visualised?
- How is power consumption managed?
- How would you secure the device and its communication?
